B
两者都时用both
和谓语动词连用时,both应放在 be动词、助动词和情态动词之后,行为动词之前
选B both 表示两者都 而all是三者或三者以上都 My parents 不就俩人嘛 所以用both 另外 both 放在系动词后行为动词前 are 是系动词 所选B
B:
both形容两者。all表三者或三者以上。parents父母只有两个人
both常用语be动词后面。
1.Both are 中both是代词pron. 作主语.eg:There are two men over there,both are from America.=There are two men over there, both of them are from America.
2.are both中both是形容词adj. 作主语同位语.eg:The two men over there are both from America."both"作主语同位语时,其位置在be动词,情态动词,助动词之后,实意动词之前.
3.Both A and B 中both是副词adv.eg:Both you and I are interested in asking questions.
